Energy storage

The global need for electricity increases and so does the expectation for clean and reliable power by integrating renewable energy sources, such as wind and solar, in the grid. One of the major challenges is that renewable energy production can be unpredictable, making grid operators hesitant to become dependent on elements they cannot control.

In parallel, networks are ageing and become more decentralized, less efficient and more congested as the energy passing through the lines increases with the energy demand. Innovative ways are needed for improving the grid’s flexibility, reliability and efficiency.

Energy storage, as a solution to the above, provides a huge number of beneficial services and cost savings to our electric grid. Large scale energy storage also allows today's electrical system to run significantly more efficiently, and that greater efficiency means lower prices, less emissions and more reliable power.

The MegaWatt control with C-Bee

We are specialists in building the perfect blocks for a safe and fully reliable MegaWatt energy storage system. Our flexible and highly configurable C-Bee power stacks controller platform allows multiple hardware and software configurations with the following key features:

Simultaneously operates a breaking resistor and/or an energy storage set of batteries or supercaps

Optical or electrical control of the power stack

Parallel operation of several units

Current limitations in boost and buck modes and for both the breaking resistor and the energy storage

External or internal start command and operation capabilities

External or internal references for different modes of operation

Additional I/O for system integration can be programmed based on customer requirement

Using the ZekaTrace™ and ZekaStream™ technology, you will be able to display the electrical characteristics and diagnose the health of the system with an unprecedented resolution for the industry. Only one such converter in your design is enough to change the way you commission the whole power plant.

Having numerous communication interfaces including Ethernet, RS485 and CANBus and utilizing Modbus, makes the integration with your industrial network an easy task. Profibus interface is also available using a Modbus-to-PROFIBUS Gateway. The integrated Modbus master allows different Modbus slaves to be attached to extend IO and functionality.

Several digital and analog inputs and outputs are available for additional programming allowing extra flexibility during the system design or even when the project is in its final phase. The integrated Modbus master allows different Modbus slaves to be attached to extend IO and functionality.

Installations

We built the control, the heart of the first hybrid drill floor system already operating on the latest Transocean drillships of type Ultradeep Water. here is a partial list of them:

Deepwater Spitsbergen

Deepwater Poseidon

Deepwater Pontus

Deepwater Proteus

Deepwater Conqueror

Deepwater Thalassa

Deepwater Nautilus

Deepwater Asgard

Deepwater Invictus

This technology is not only environmental friendly by utilizing megawatts of energy that were previously wasted, it also equalizes the load of the whole power plant thus reducing maintenance and increasing robustness.
